Alternatively, these can be with worldwide NTSC, PAL, and SECAM standards into bypassed for manual settings. 4:2:2 component video data compatible with 20-/16-/10-/8-bit The fixed 54 MHz clocking of the ADCs and datapath for all CCIR 601/CCIR 656. modes allows very precise, accurate sampling and digital filtering. The advanced, highly flexible digital output interface enables The line-locked clock output allows the output data rate, timing performance video decoding and conversion in line-locked, signals, and output clock signals to be synchronous, asynchronous, clock-based systems. This makes the device ideally suited for a or line locked even with 5% variation in line length. The output broad range of applications with diverse analog video character- control signals allow glueless interface connections in most istics, including tape-based sources, broadcast sources, security applications. The ADV7188 modes are set up over a 2-wire, 2 and surveillance cameras, and professional systems. serial, bidirectional port (I C compatible). The accurate 12-bit ADC provides professional quality video SCART and overlay functionality are enabled by the ability of performance and is unmatched. This allows true 10-bit the ADV7188 to process CVBS and standard definition RGB resolution in the 10-bit output mode. signals simultaneously. Signal mixing is controlled by the fast blank pin. The ADV7188 is fabricated in a 3.3 V CMOS process. The 12 analog input channels accept standard composite, S-video, Its monolithic CMOS construction ensures greater functionality and component video signals in an extensive number of with lower power dissipation. It is packaged in a small, Pb-free, combinations. 80-lead LQFP. Rev. A Information furnished by Analog Devices is believed to be accurate and reliable.
